The normal modes of a continuum solid endowed with a random distribution of line defects that behave like elastic strings are described. These strings interact with elastic waves in the bulk, generating wave dispersion and ...

Background: Astaxanthin is a potent antioxidant with increasing biotechnological interest. In Xanthophyllomyces
dendrorhous, a natural source of this pigment, carotenogenesis is a complex process regulated through ...

We complete all local spinor norm computations for quater-nionic skew-hermitian forms over the field Qof rational num-bers. This can be used to compute the number of classes in a genus of skew-hermitian lattices of rank ...
